. However, the standard cost frontier model yields biased efficiency scores because it ignores technological heterogeneity … between hospitals. In this paper, efficiency scores are derived from a random intercept and an extended random parameter … efficiency according to the standard model gain up to 12 percentage points, serving to highlight the importance of heterogeneity …

Existing methods for the measurement of technical efficiency in the dynamic production models obtain it from the … dynamic evolution of efficiency that is explicitly optimized by the firm. This paper introduces a new conceptualization of … efficiency that directly enters the firm's intertemporal production decisions and is both explicitly costly and endogenously …

We develop a novel unified econometric methodology for the formal examination of the market power -- cost efficiency … nexus. Our approach can meaningfully accommodate a mutually dependent relationship between the firm's cost efficiency and …'s market power and efficiency as well as allows for different hierarchical orderings between the two, enabling us to …
